摘　　要：为促进高油玉米品种的选育,以高油玉米自交系GY237和普通玉米自交系OH43杂交组合的6世代P1,P2,F1,B1,B2,F2为试验材料,采用主基因+多基因遗传模型分析方法,对玉米籽粒含油量的遗传特性进行研究。结果表明:玉米籽粒含油量的遗传符合一对加性+显性主基因+加性-显性-上位性多基因遗传模型(D-0),B1,B2,F2的主基因遗传率分别为57.665 8%、0.763 4%和42.742 4%,多基因遗传率分别为25.556 2%、77.373 7%和42.742 4%,说明主基因和多基因在同一组合不同世代间有较大的差异。In order to promote the breeding of high oil maize, taking six generations （P1 , P2, F1 , B1 , B2 , F2 ）of GY237（high oil content inbred line）× OH43 （normal inbred line）as basis materials, major gene plus polygene mixed inheritance model was used to analyze the genetic of oil content. The results showed that the heredity of maize kernel oil content matched one additive-dominant-epitasis plus additive-dominant polygene mixed inherit- ance model：the heritability of major gene of B1 ,B2 ,F2 was 57. 665 8% ,0. 763 4% and 42. 742 4% respective- ly,and the heritability of polygene was 25. 556 2%, 77. 373 7% and 42. 742 4% respectively. Therefore, the heritability of oil content of maize kernel was remarkable different between main gene and polygene in different generations of same hybrids.
